The Grande Supreme 100 is in reference to speed, and amber is in reference the lens color. This light is intended for lower visibility race applications while still mashing the throttle down. With a copper circuit board producing enough power to power a city, this 140-watt light is engineered to maximize visibility in lower visibility race applications. With a mix of spot and flood optics and the ability to program your light, you can truly create the ultimate race light no matter what you are facing.
